In any triangle, who is the betrayer, who the unseen rival, and who the humiliated lover? Oneself, oneself, and no one but oneself!
Music is one of my big interests - I once had a rather fanciful ambition to be a singer - and of course music is philosophically fascinating. What it is for music to express emotion strikes me as one of the most difficult questions - it's hard to say what it precisely means, although it plainly does mean something. But whenever I have tried to say something about this, it has come out as either banal or pretentious or both.
